SEARCH-LIGHT MOUNTING.

Specification of Letters Patent.

Patented Aug. 3, 1.909.

Application filed June 29, 1908. Serial No. 440,957.

To all whom it may concern:

Be it known that I, ERNEST C. EVERETT, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in Search-Light M ountings, of which the following-is a specification. This invention relates to that class of mountin s for searchlights which comprise a forked bracket having bearings at its upper end in which the searchlight is supported by horizontal pivots, so that the axis of the searchlight can be moved or adjusted in a vertical plane, and in which the bracket can be turned about a vertical axis, so that the axis of the Searchlight can also be adjusted or revolved in a horizontal plane. Searchlights of this kind are usually mounted upon the roof or deck of the pilot house or cabin of the boat and are provided with an upright adjusting rod which extends from the bracket downwardly through the roof or deck to a point in convenient reach of the pilot or other operator, This rod is usually connected at its upper end by a lever and link mechanism with the searchlightand the latter is adjusted or moved in a vertical plane by movin the rod up or down and is adjusted or revolved in a horizontal plane by turning the rod.

The object of this invention is to simplify the mechanism by which the adjusting rod is connected with the Searchlight.

In the ace mpanying drawings: Figure 1 is a side elevation, partly in section, of asearchlight provided with this improved actuating mechanism. Fig. 2 is a front elevation thereof Fig. 3 is a side elevation, partly in section, of the searchlight, on an enlarged scale. Fig. 4 is a fragmentary bottom plan view, partly in a section taken in line {i4, Fig. 3. tion in line 55, Fig. 1, on an enlarged scale. Fig. 6 is a horizontal section in line 66, Fig.1. Fig. 7 is a fragmentary longitudinal section of the lower portion of the searchli ht. Fig. 8 is a transverse vertical section 1n line 8-8, Fig. 1, on an enlarged scale.

Like reference characters refer to like parts in the several figures.

A represents the roof or deck-of the cabin or pilot house of a' boat or launch. B the upright standard or socket which is secured upon the same and which receives the cylin- Fig. 5 is a horizontal sec,

drical'stem 10 of the forked bracket C in which the case D of the searchlight or lamp is journaled by horizontal pivots 11. The bracket is provided for this purpose with bearings 12 13, of which the bearing 13 is split and provided with a tension screw 14 by which the frictional resistance can be regulated or the lamp case can be rigidly clamped in position. The standard or socket B also is split and provided witha tension screw 15 for regulating the friction or clamping the bracket in position.

16 represents the gas burner in the lamp case and 17 the gas pipe provided with the usual nipple 18.

E represents .the upright adjusting rod which is arranged within the stem 10 of the bracket and extends above and below the stem, the lower end of the rod being provided with a handle. The upper portion 19 of this rod is square or angular and the bore of the stem is of similar form so that the rod can be moved up or down in the stem for swinging or tilting the lamp case up .or down, while a rotary movement of the rod causes the stem to turn with the rod in the socket B and to revolve the bracket and the lamp case.

20 represents a rigid actuating arm which extends from the u per end of the rod to the under side of the 12111;) case in the longitudinal direction of the latter and preferably forwardly, as shown, and 21 represents a longitudinal guide which is arranged on the under side of the lamp case and with which the free end of the arm has a sliding connection, so that the vertical movement of therod causes the lamp case to be swung vertically on its ivots. The guide is provided with a longitudinal slot 22 into which the arm 20 extends and in which it can move back and forth! The arm' engages against the u er and lower sides of the guide, prefera y by means of upper rollers 23 and lower rollers 24 mounted on studs proj ecting from opposite sides of the arm. The

guide is preferably curved lengthwise and presents its convex side downwardly, wherey the resistance of the lamp case to movement-by the adjusting rod is reduced.

The adjusting arm being rigidly secured to or formed on the adjusting rod and arranged on the under side of the lamp case, as described, the arm engages with the lamp case in a very direct manner, whereby the adjust' ing mechanism is rendered very simple and F movable lengthwlse thereof, substantlally as compact and also easy of manipulation.

l claim as my invention: 5

1. The combination with a supportingi bracket and a lamp case supported therein by horizontal pivots, of an upright adjusting 5 rod movable up and down in said bracket and provided with an actuating arm rigidly connected with said rod, and a connection between said arm and case which is slidable lengthwise of said case, substantially as set forth.

2. The combination with a supporting bracket, a su )port in which said bracket is ported in said bracket by horizontal pivots, of an upright adjusting rod movable up and 1 down in said bracket, means for turning said bracket in its support by said rod, and an actuating member rigidly connected with said rod and having a connection with said case which is arran ed forwardly of said pivots and is slidable lengthwise of said case, i substantially as set forth.

3. The combination with a supporting bracket, of a lamp case supported thereon by horizontal ivots and rovided on its under 1- side with a ongitudina slotted guide, and an upright adjusting rod movable up and down on said bracket and provided with an actui ating arm which extends into said slot and i engages said guide, on which said arm is set forth.

4. The combination with a supporting bracket, of a lamp case supported thereon by horizontal pivots and provided on its under side with a longitudinal guide, and an upright adjusting rod movable up and down on said bracket and provided'with a rigid actuating arm which is provided with upper and lower rollers engaging against the u per and lower sides of said guide, substantia ly as set forth.

5. The combination with a sup porting side with a longitudinal slotted .guide, and

" an upright adjusting rod movable up and down on said bracket and provided with a rigid actuating arm which extends into said slot andis provided on opposite sides with upper and lower rollers engaging against the up er and lower sides of said guide, substantia ly as setforth.

Witness my hand in the presence of two subscriblng witnesses.
